Method of manufacturing a floor board

1. A method of manufacturing a floor board, comprising:

supplying a panel; wherein said panel comprises a substrate and a decorative basic panel that is directly printed on the substrate or laminated thereon;

printing a surface removing substance onto a surface of the panel in a predefined pattern for removing a portion of the surface of the panel at the predefined pattern, wherein the predefined pattern substantially corresponds to the decorative basic pattern being present on the panel, and wherein the step of printing is digitally controlled; and

removing any reaction products of the surface removing substance and the panel.

2. The method according to claim 1 , wherein the surface removing substance is printed onto the panel by first printing a liquid onto the panel in said predefined pattern, and then providing an intermediate substance to the liquid, wherein the intermediate substance or the liquid together with the intermediate substance form the surface removing substance.

3. The method according to claim 2 , wherein the intermediate substance comprises a powder.

4. The method according to claim 1 , wherein the panel is a flexible sheet, the method further comprising, after printing the surface removing substance onto the surface of the panel, laminating the substrate to the panel so as to form the floor board.

5. The method according to claim 1 , wherein the surface removing substance is activated by an activation device for reaction of the surface removing substance with the panel surface.

6. The method according to claim 5 , wherein said surface removing substance is activated by a heat source, UV radiation or laser beam.

7. The method according to claim 1 , wherein said substrate is made of HDF, WPC, polymer composite, engineered polymer, LVT or PVC.
